CHENILLE-MAKNG' MACHINE.

Application led June 20, 1925.

This invention relates to improvements in machines for making chenille generally, and, particularly, to machines for making chenille for various purposes of ornamentation wherein the pile thereof is formed of tinsel threads.

The object of the invention is to improve the means for carrying the pileforming threads and delivering them to r cessity of delivering two or more threads from a single spool to provide the requisite number of threads for the formation of the desired pile, and to so construct and arrange the parts for carrying the threads for forming the pile with relation to the pile forming elements of the machine that a single thread may be delivered from each of the spools supplying the pile threads for the production of chenille having the desired numerous pile threads.

lith the forgoing and related objects in view, the invention resides in the novel construction, combination and arrangement of parts hereinafter described and claimed.

'in the accompanying drawings, illust-rat- `ing my invention.,

Figure 1 is a side view of a portion of a chenille making machine embodyingmy invention.

Figure 2 is a horizontal section of the machine, on line 2 2 of F ig. 1.

Figure 3 is a diagrammatic. view showing the arrangement of the pile thread spools and the manner in which the pile threads are delivered therefrom to the central thread guiding ring.

Figure 4 is a side view of the core plates around which the pile threads of the chenille are wrapped.

Referring to the drawings, 3 designates the frame of the machine which `is provided with a fixed bearing or bracket 4.

Secured within the bearing 4 is 4the rearward end portion of a horizontally arranged, hollow shaft 5 through which two Serial No. 38,449.

warp threads 6 are drawn in the direction of the arrows to form parts of the cores of two strips of chenille.

,secured to the forward end portion of the hollow shaft 5 are the oppositelyv disposed vertical members 8 of two angle plates 9 having forwardly extending horizontal members 10 between which is secured' a core plate 11 for receiving the threads for forming the pile of the chenille. The horizontal. members 10 of the angle plates 9 have wing portions 1 2 which extend outwardly beyond the sides of the forward end of the core plate 11 and which are shaped to provide inclined sides which converge forwardly to the sides Aof the core plate, as shown in Fig. 2. The core plate 11 extends forwardly from the wings 12 and the warp threads 6 are guided by and between the upper and lowerwings 12 along the sides of the plate 11, in close proximity thereto, to and between the sides of the plate 11 and a pair of horizontally disposed guiding wheels 13 arranged outwardly of the vsides of the forward end portion of the plate 11 in spaced relation to the wing portions 12 of the angle plates 9, as clearly shown in Fig. 2. y

The periphcries of the wheel 13 are cir- 4cuinferentially grooved to receive the warp threads and the side edge portions of the core plate 11, and also to receive two wires 14 drawn from a suitable source over a guide rod 15 to and through the grooves in the wheels 13 and around the rearward portions thereof until they meet the warp threads 6 between the plate 11 and wheels 13.

After the wires 14 meet the warp threads 6 they are drawn onwardly with themrin the direction of the arrows and the wires and threads are twisted together from and beyond about the-points where they meet, to form the cores of two strands of chenille, in the usual well known manner.

' The wheels 13 are carriedby the rearward arms 16 of two levers 17 which are fulcrumed on a vertically extending shaft 13 which'is supported by the machine frame. The levers 17 cross each other and the rearward arm 19 of one of the levers 17 has a rod 2O pivotally connected thereto which extends slidably through and beyond a part of the rearward end of the arm 21 of the other lever 17. The free end of the rod 2() carries a head 22 between which and the lever arm 21 a spring 23 encircles the rod 2O and tends to move the lever arms 19 and :31 toward each other, thereby tending to move the lever arms 16 and the wheels 13 carried. thereby toward each other. rlll-ius the spring` 23 holds the wheels 13v yieldingly in contact with the slides of the core plate 11 or in contact with the wires 14 and threads 3 passing between the sides of the core plate 11 and the wheels 13.

Arranged within an opening in the forward endI portion of the core plate 11 and between the guiding wheels 13 ,is a pair of cooperating cutter discs 24. The lower disc 24 is mounted to turn on an arm 25 which is tixed to the vertical shaft 18, and the upper disc 21 is mounted to turn on an a m 23 which' is carried by the shaft 18 and adapted to turn on theaXis thereof, so that the upper disc 24- may be pressed yieldingly against the lower disc Q4 by the action of a spring 27 which encircles the shaft 18 and which has ,its lower end engaged with the arm 26 and its upper end engaged with a collar 23V fixed. on the shaft 13. p

The threads which are to form the pile of th-e chenille are wrapped around the core plate 11 and the warpv threads 6 passing,` along` the sides thereof, and they are carried by the thread-s 6 into the bite of the cutter discs 24 which are located slightly in advance of a line drawn between the centers of the wheels 13 to cut or sever the pile threads at the proper place with relation to the passage of the pile threads be tween the core threads G and core wires lt, and the twisting` of the ,threads G and wiresl 1st for the proper formation of the chenille. The cutter discs 24 are adapted to be driven in the usual manner during' the operation of the machine to effect the cutting` operation.

The construction and operation of the parts thus far described are well known to persons skilled in this art, and, therefore, no detailed description thereof is deemed .necessary herein.

I shall now describe the means forming the subject of my invention for carrying the pile forming threads and delivering them to and wrapping them around the core plate 11 and the forwardly moving warp threads 6.

Rotatably mounted on the hollow shaft 5 between the bearing 1 and a flange or collar 7 on the forward end of the shaft isa sleeve 30 which carries a member 3l comprising` a disk-like body 32 and a een tral sleeve or hub 33 which is secured to the sleeve 30 by means of set screw 3a,

ai', when the sleeve is rotated, the

member 31 will be rotated. The sleeve 3U has a gear wheel i5 formed thereon by end porti-ons of the spindles 33 and 39 are provided with pins 40 which ei-:tend transversely through openings therein and which retain the spools upon the spindles. Washers l are interposed between the pins L10 and the spools and the pins t0 and washers 41 are removable from the spindles to permit filled spools to be placed thereon. and empty spools to be removed tl'ierefrom,

Projecting forwardly from the forward end of the sleeve or hub 33 of the rotatable member 31 is a pair of arms 4t2 carryingl a ringarranged concentric with the axis of rotation of the member 31 to guide or `guard pile-forming threads delivered from the spools 36 and 37, as will be presently described.

The axes of the spindles 33 and 3S) and the spools 36 and 37 carried thereby are inclined with respect to the axis of rotatfon of the member 31 and they diverge from the forward face of the body 32 of the member 31 and from the axis of rotation of lthe member, as clearly shown in the drawings, and the axes of the outer spindles 39 and spools 37 are more nearly parallel to the artis of rotation of the member 31 than the axes of the inner spindles 33 and spools 36, as illustrated.

The spools 37 of the outer serfes thereof are more numerous than the spools 33 ot' the inner series, and the axes of pairs of neXt adjacent spools 39 of the outer series intersect separated lines which radiate from the center of the member 31 and pass bctween the axes of pairs of next adjacent spools 33 of the inner series, so that threads 41o drawn from two next adjacent spools 39 of the outer series may pass between two nextadjacent spools 36 of the inner series to the ring` L13 without contacting' with the spools 36 or the threads carried thereby, and so that threads 46 drawn from the inner spools 36 may pass to the ring 43 .'fithout contacting with the threads drawn from the outer spools 39, as shown in Fig. 3.

During' the rotation of the member 31 the pile-forn'iinp; threads and L13 are drawn from the spools 39 and and wrt. around the core plaie 11 and the threads G moving forwardly along the thereof, and the pile threads 45 and 43 are lll? carried forwardly by the threads G as rapidly as the convolutions of the pile threads are formed around the core plate ll and threads 6. rl`he relation of the axes ot tie spindles 3S and 39 to the axis ot rotation of the member 3l is such that the spools 36' and 37 and washers 4l are pressed against the pins 40 by centrifugal action with suhicient l'orce to create enough friction between the parts to retard the turning movements of the spools 36 and 8T sulliciently to cause the threads and 46 to be drawn from the vspools under the desired degree of tension.

rI`he axes ol' the inner and outer spools 36 and 37 are so disposed with respect to the ring 43 that, as the threads 45 and 46 are drawn trom the spools to the core plate ll, each thread 45 and 46 will maintain substantially a const-ant angle with respect to the axis of rotation ot the member 3l, and cach thread. 45 and 46 will be permitted to be delivered from all parts ot its spool between thc ends thereof withoutsubst itially varying the length of that por i each thread which extends between its spool and the guiding ring 43, thereby preserving substantially a constant tension on all threads 45 and 4G.

The member 31 is adapted to be rotated by the usual mechanism of the machine geared to the wheel 35, and, during its rotation, the pile forming threads 45 and 46 are drawn from the spools 37 and 36, formed into convolutions around the core plate 11 and warp threads 6, the convolutions are carried forwardly by the warp threads 6 to the. wires 14 and cutter discs 24, the convolutions are centrally cut by the discs 24 and the cut convolutions are bound between the twisted threads 6 and wires 14 to form two strips of chenille.
